For your scheduling needs: quartz or jcrontab

For your scheduling jobs, I do recommend quartz http://www.opensymphony.com/quartz/

Quartz is a full-featured, open source job scheduling system that can be integrated with, or used along side virtually any J2EE or J2SE application - from the smallest stand-alone application to the largest e-commerce system.
Quartz can be used to create simple or complex schedules for executing tens, hundreds, or even tens-of-thousands of jobs; jobs whose tasks are defined as standard Java components or EJBs.
The Quartz Scheduler includes many enterprise-class features, such as JTA transactions and clustering.


For a simple cron replacement http://jcrontab.sourceforge.net/

Provides a system to run Classes/Threads/main/EJB/Methods/NativePrograms... at a given time.
Provides a parser of crontab-like files that are fully compatible with UNIX-POSIX crontab files
